N-TOP Con has become one of the mainstream technical routes for the industrialization of N-type batteries. Boron diffusion is mainly used to make PN junctions on the front side in battery manufacturing, which is one of the key processes. The furnace body is specially designed for high temperature process (900~1100 ℃), which can effectively prevent the deformation of the furnace body and prolong the service life of the furnace body; Rapid cooling furnace body: The latest patented technology makes the furnace body temperature drop to the required temperature quickly, the cooling rate is increased by more than 25%, and the temperature uniformity in the furnace tube is obviously improved; Advanced cascade temperature control and intelligent cooling technology, improve temperature stability and temperature control accuracy, and reduce temperature setting time; The advanced fully closed-loop pressure control system can accurately detect and control the air pressure in the process chamber in real time; Efficient exhaust gas treatment system, dry and wet separation, automatic discharge, greatly extend the maintenance cycle, reduce maintenance costs, and ensure the operating rate and process stability; Innovative non-landing process method, the quartz boat is suspended during the process, which can effectively reduce the stress and deformation of the quartz tube, reduce the stickiness between the quartz devices, and prolong the service life; The unique furnace door sealing design realizes the isolation of the metal and the reaction chamber, reduces heat loss, greatly prolongs the service life of the sealing ring, and ensures the stability of the pressure;
